Millions of people in Pakistan have been forced from their homes by a tide of floodwater after five days of heavy monsoon rains.
The authorities said the country is once again on the brink of a national "calamity" and that the flooding is comparable to a similar disaster in 2010.
In flooding last year, 2,000 people were killed and 11 million lost their homes.
The worst affected area is Sindh in the south of Pakistan.
Provincial chief minister Syed Qaim Ali Shah said more than five million people have been made homeless and thousands of villages have been swallowed up by the rising waters.
It is now a desperate time for the displaced as they struggle to find higher ground to build shelter and stay safe. more
